ErrorLens is a developer-focused debugging tool that analyzes runtime errors and code snippets to identify root causes and suggest multiple resolution paths with confidence scoring.
Debugging is one of the most time-consuming parts of development. Developers often waste time:
- Interpreting vague error messages
- Tracing issues across unfamiliar code
- Searching through forums for possible fixes
ErrorLens reduces debugging time by providing structured, context-aware analysis of errors.
Developers can input an error message and related code, and the system will:
- Explain the error in simple terms
- Identify the root cause
- Suggest multiple possible fixes
- Provide a confidence score for each analysis
- User submits an error and code snippet
- Backend processes and enhances the input with pattern detection
- AI model analyzes the context using structured prompting
- Response is parsed into a consistent JSON format
- Frontend displays results in a clean, developer-friendly UI
- Structured error analysis (not raw AI output)
- Root cause identification
- Multiple fix suggestions
- Confidence scoring system
- Developer-focused UI with code editor support
Frontend:
- React + TypeScript
- Tailwind CSS
- Monaco Editor
Backend:
- Node.js + Express + TypeScript
AI Integration:
- OpenAI / Claude API with structured prompting
Frontend (React) ↓ Backend API (Node.js) ↓ AI Processing Layer
This project focuses on:
- Practical developer utility
- Clean and structured output
- Minimal but effective UI
- Real-world debugging workflows
- Stack-specific error detection (React, Node, MongoDB)
- Error history tracking
- Authentication and saved sessions
- Enhanced confidence scoring using heuristics
Instead of building a generic AI wrapper, ErrorLens focuses on a real developer pain point—debugging—and delivers a structured, actionable solution.
This project demonstrates:
- API design and backend structuring
- Prompt engineering and response shaping
- Frontend state management and UI composition
- Problem-solving with AI integration
